fix(bundling): ensure vitest timestamp files are ignored (#29418)

## Current Behavior
Vitest TS config files produce timestamp temp files during project graph
creation which are cleaned up.
However, the creation and deletion of these files triggers the daemon to
recalculate graph.
It ends up in a loop.
The vite timestamp files were already added to the gitignore to prevent
this.

## Expected Behavior
Add vitest timestamp files to gitignore
